Title: Grating coupler
Inventor: HANADA KEIJI
IPC: G02B6/34
Filed: 1985-06-14
Abstract: PURPOSE:To obtain exit light having a desired intensity distribution and particularly Gauss distribution by determining the depth of a grating according to the desired intensity distribution of the exit light along the progressing direction of guided light and the intensity of the guided light emitted and attenuated according to such distribution. CONSTITUTION:The depth h(x) is so formed as to be larger toward the progressing direction of the guided light in the grating coupler formed on the optical waveguide so as to lead the guided light propagating in the optical waveguide formed on a substrate to the outside. An electron ray resist is first coated on the substrate to manufacture such grating. The grating pattern is then drawn by an electron beam so as to have the dose distribution periodic in the direction intersecting orthogonally with the scanning direction of the electron beam and in such a manner that the dose at each period corresponds to the depth h(x) in an electron ray drawing device. The resist patter of which the thickness periodically changes and the thickness corresponds to the depth h(x) is formed if the resist is developed after the drawing. The substrate is finally dry etched by an ion beam etching, etc. through the resist pattern.

Title: Printing device, print control for printing device and storage medium storing program to be read by computer
Inventor: HOSODA OSAMU
IPC: B41J21/00
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent a transparent recording medium already in the process of printing from being discarded by interpreting a state in which output data to be transferred to a printing part after being developed in memory is erroneously transferred and printing distributed data on both faces of the transparent recording medium based on the interpretation results, in accordance with the processing rate of printed matter. SOLUTION: A forecast arithmetic process interprets whether time required for received data to be developed into bit image data under printing process can catch up with a printing speed (1). Then if the forecast arithmetic process interprets that the time does not catch up with the printing speed, that is, an overrun error is generated, information on the print range of an image printed on the front face of a recording medium during the period of time upto the generation of the error is stored in RAM (3). Next, the printing process is set to the double-sided printing mode (4), and an image not printed on the front face is printed on the rear face by developing it symmetrically to the right and to the left as a bit map as if the image were reflected on a mirror, using input data stored in RAM and the print range of an image printed on the front face (5).  The input data stored in RAM and the print range of an image printed on the front face are delected (6).
